Problems:
Apex seal wear
Due to the unique design of the rotary engine, the apex seals can wear out faster than traditional piston engine components, leading to compression loss and reduced performance.
Oil consumption
Rotary engines, such as the Mazda 13BE in the RX-7, are known for higher oil consumption, which requires vigilant monitoring and frequent top-offs.
Cooling system issues
The rotary engine generates more heat compared to piston engines, making the cooling system critical. Problems with the cooling system can lead to overheating and engine damage.
Flooding
The RX-7's rotary engine is prone to flooding, especially if it is started and stopped without reaching operating temperature. This can make the engine hard to start.
Carbon build-up
The design of the rotary engine can lead to carbon build-up on the rotor faces and combustion chambers, which affects engine efficiency and performance.
Vacuum leaks
The RX-7’s rotary engine relies heavily on vacuum systems. Leaks can cause idling issues, poor performance, and even stalling.
Fuel injector problems
Due to the high-revving nature of the rotary engine, fuel injectors can become clogged or fail, leading to poor fuel delivery and engine performance issues.
Ignition system failures
The rotary engine uses a dual-spark plug system for each rotor, and issues with the ignition system can lead to misfires and reduced engine efficiency.
